我中心研究员李姗姗和刘倩在国际知名期刊《Ecological Indicators》2024年1月刊(Volume 158, January 2024, 111374)上发表了题为“Research on water quality improvement effects of China’s Battle against Black-Odor water bodies”的学术论文。
鉴于中国城市化进程的持续发展,黑臭水体的扩散已成为城市环境中的首要困境。自2015年以来,中国出台了一系列旨在缓解黑臭水体困境的政策。然而,在监测部门层面评估黑臭治理对水质影响的研究很少。本研究构建了黑臭综合指数(BOCI),以评估中国黑臭水体在监测断面层面的修复效果。利用2016—2018年国家监测段的月度水质数据,应用BOCI指数评估黑臭水体水质改善情况,相关水段水质改善情况,定量分析黑臭水体防治效果。结果表明,中国黑臭水体水质显著改善。值得注意的是,这种改善在面临更不利环境条件的水体中最为明显。“黑臭水体抗击”行动有效地迫使地方政府通过检查、调查和其他措施解决与黑臭水体相关的问题,取得了良好的结果。

Abstract
Given the sustained momentum of China's urbanization, the proliferation of black and odorous water bodies has emerged as a foremost predicament within urban settings. Since 2015, China has enacted a succession of policies aimed at mitigating the predicament of black and odorous water bodies. Nevertheless, there is a paucity of research assessing the impact of black-odor governance on water quality at the monitoring-section level. This study constructs the Black and Odorous Comprehensive Index (BOCI) to appraise the efficacy of remediating black and odorous water bodies at the monitoring-section level in China. Utilizing monthly water quality data from national monitoring sections spanning 2016 to 2018, the BOCI index is applied to evaluate the improvement in water quality within black and odorous water bodies, the enhancement of water quality in associated sections, and to quantitatively analyze the remediation effects resulting from the battle against black and odorous water bodies. The results indicate that a significant enhancement in the water quality of black and odorous water bodies in China. Notably, this improvement is most pronounced in water bodies facing more adverse environmental conditions. The Battle Against Black-Odor Water Bodies initiative has effectively compelled local governments to address issues associated with black and odorous water bodies by means of inspections, investigations, and other measures, leading to favorable outcomes.
